Concrete slab and beam forming system

A slab form comprising:

• a first plank;
• a second plank pivotally attached to said first plank;
• a first facing integral with said first plank;
• a second facing integral with said second plank;
• means for releasably securing said first and second planks against movement with respect to each other in a position in which said first and second facings are positioned in a first coplanar position;
• means for securing said first and second planks against movement with respect to each other in a position in which said first and second facings are positioned in a second substantially perpendicular position;
• and
• a caster retractably received within said second plank for moving said slab form over a surface.

A slab form comprising:

• first and second planks;
• first and second facings, each of said first and second facings being integrally mounted to said first and second planks, respectively;
• means for releasably securing said first and second planks against movement with respect to each other in a position in which said first and second facings are positioned in a first substantially coplanar position;
• means for securing said first and second planks against movement with respect to each other in a position in which said first and second facings are positioned in a second substantially perpendicular position;
• and
• a caster mounted on the end of said second plank and movable between a first retracted position when said first and second facings are positioned in said first substantially coplanar position and a second position for moving said slab form over a surface when said first and second facings are positioned in said second substantially perpendicular position.
